What are some steps to take as a freshman towards preparing for university?

My advice would be to use your summers and time-off wisely. Find something you're passionate about and start volunteering. If you're interested in the medical field look for ways to help with hospitals or retirement homes. Also, you will need letters of recommendation, so start building relationships with people in your community who are doing the types of jobs you are interested in. Get involved with organizations that go out together and volunteer; this could be churches, rotatory clubs or organizations at school. If there isn't a volunteer organization at your school, you should start one! Becoming part of a volunteer organization helps you meet new people who can show you more opportunities.

Finally, do something that is just for you - something that makes you unique. Paint, dance, go bird watching, blog or create video tutorials. Cultivating your interests will make you a more interesting person!

Colleges, scholarship essays and teachers have asked me many times why I have chosen my major. It was nice to be able to say, "Because once I had a summer job that opened my eyes to the rest of my life."

As a freshman, you don't really need to worry about what you need to be doing to prepare yourself for a university. All you should focus on as a freshman is just getting the best grades you can, as they will be shown on your application for any college you apply for, and maybe getting yourself into some extra curricular activities such as sports or clubs and maybe keep your eye open for a job for when you turn 15/16. The real thinking and talking and preparation for a university will start your junior year of high school.
